Patent CA-2284386-A1 (CA)
Inventor: LAILLY PATRICK
IPC: G01V1/30
Filed: 1999-09-29
Abstract: Méthode de migration avant sommation (« prestack migration ») permettant d'imager une zone souterraine, pour un modèle de vitesses donné de complexité arbitraire. - Au moyen d'outils classiques de modélisation de la propagation et de la rétropropagation des ondes, la méthode permet d'obtenir des images migrées élémentaires associées aux valeurs que prend un paramètre et la somme des images obtenues pour les différentes valeurs du paramètre (sommation après migration) et ceci aussi bien dans le domaine profondeur que dans le domaine temps. Cette migration est obtenue à un prix (coût de calcul) avantageux car indépendant du volume de résultats calculé et du nombre de traces sismiques enregistrées. Seul le volume de la zone dans lequel les ondes se propagent, la complexité des événements à imager et la précision souhaitée ont une incidence sur le coût du calcul. On obtient ainsi des images volumiques en prenant en compte l'ensemble des traces sismiques. On a ainsi la possibilité de mettre en oeuvre une procédure de migration par ondes planes dans le cas où l'acquisition ne permet pas la synthèse de la réponse de la subsurface à une excitation onde plane, réponse requise en entrée dans les algorithmes classiques de migration par ondes planes. - Applications à l'imagerie d'interfaces géologiques ou hétérogénéités d'une partie de zone souterraine.

Patent CA-2284713-A1 (CA)
Inventor: MATSUI MITSURU
IPC: G06Q10/04
Filed: 1999-01-21
Abstract: An integer Z101 is divided by an integer I102 to obtain a remainder R109. The integer I102 includes a polynomial of power of a basic operational unit of a computer. In this way, the integer I for divisor is limited based on the basic operational unit of the computer, thus a shift operation, which is required for a conventional operation method, can be eliminated. The remainder can be calculated by only addition and subtraction. Accordingly, a code size becomes compact and the remainder of the integer can be calculated at a high speed.

Title: Method and apparatus for removing toxic substances from waste marine products
Inventor: ICHIKAWA HIROYUKI
IPC: A23L17/40
Filed: 1999-10-08
Abstract: In an electrolytic bath, an extraction part extracts heavy metal in the internal organs of scallops into an acid solution. A direct current voltage is applied between electrodes, which are provided in the acid solution, to deposit the heavy metal in the acid solution on the electrodes. If the deposit efficiency deteriorates, the polarity applied between the electrodes is reversed from the polarity in the deposition of the heavy metal in a neutral or alkali electrolytic solution. Consequently, the heavy metal is removed from the electrodes. Since arsenic is dissolved in the acid solution, an alkali liquid and a flocculant are added to the acid solution to sediment arsenic.

Abstract: A system (10) for detecting the position of a catheter (30) in a patient includes three sets of reference electrodes (20), with one set disposed on each of the mutually orthogonal (X, Y, Z) axes. A signal processor (14) measures the differential voltage indicative of impedance between a detection electrode (38) disposed on the catheter (30), and each electrode of each of the three sets of reference electrodes (20) in order to determine the X  coordinate, Y coordinate, and Z coordinate of the catheter (30). The detected position of the catheter (30) is recorded, and the detection of subsequent catheter positions is performed relative to the recorded catheter position.  The difference between subsequent catheter positions and the recorded position relative to the X, Y, Z axes is displayed in order to facilitate re-positioning of the catheter (30) at the recorded position. Optional EKG and/or respiratory sensors may be used to synchronize the catheter position detection in order to reduce detection inaccuracies due to EKG and/or respiratory artifacts.

Title: Method for recycling asphalt material
Inventor: ZICKELL THOMAS J
IPC: B02C19/18
Filed: 2000-05-26
Abstract: An asphalt based material recycling system and method is used to recycle asphalt materials, such as asphalt shingles and tar paper that include granules, fibers or other particles. The asphalt material is simultaneously heated and milled in a heated milling apparatus, such as a heated ball mill, to reduce the asphalt material including granules to a fine mesh in suspension in liquid asphalt. Excess moisture is removed from the asphalt material being recycled by continuously venting the heated milling apparatus. The heated milling apparatus preferably includes a rotatable milling vessel rotated at an acute angle with respect to the horizontal plane and having an opening that provides continuous venting. The shape of the milling vessel allows the liquid level inside the milling vessel to have a liquid head above the outlet region of the milling vessel, for facilitating milling. The rotatable milling vessel includes a plurality of mixing members, such as rods or paddles, extending from an interior surface to enhance milling and to pull the asphalt material being recycled under and into the liquid slurry. The asphalt material recycling system further includes a filter apparatus for filtering reduced asphalt and removing foreign objects therefrom.

Abstract: A method and apparatus for implementing multicast in a space-based communication system is disclosed. The present invention allows for the use of a buffer in which to store data packets prior to replication in a multicast application. The present apparatus includes a buffer (102), a header memory (103), and an ASIC (101) to store and extract received data packets and replicate them as required. The ASIC (101) includes a switch interface (201), a queue manager (203), a header processor (205), a holding buffer (207), and a arbitration interface (209). The switch interface (201) is connected to the queue manager (203). The queue manager (203) is connected to the buffer (102), the header processor 205, the holding buffer (207), and the arbitration and switch interface (204). The header processor (205) is connected to the header memory (103). The header processor (205) and the holding buffer (207) are connected to an arbitration and switch interface (209), whose output, in turn, is fed back through the switch matrix routing fabric (211) for routing and eventual downlink transmission. The method includes the steps of receiving data packets from the switch matrix routing fabric (302); storing the information payload and the header in the buffer(304); and extracting the information payload and header from the buffer (306). The method further includes the steps of buffering the information payload to the holding buffer (308); provisioning the header to the header processor (310); addressing the header memory (312); merging the new header obtained from the header memory with the information payload (314); and performing subsequent processing on the assembled cell (316). The latter two steps are repeated until all replicated cells are assembled and sent on for routing and eventual downlink transmission.

Patent CA-2325451-A1 (CA)
Inventor: FRANZEN RAINER
IPC: F16L13/14
Filed: 1999-02-23
Abstract: The invention relates to a pipe connection, consisting of a press fitting with at least one section which has a torus-like cross-section and which accommodates a sealing ring, an adjoining cylindrical section oriented towards the insertion end and/or such a section oriented away from the insertion end. The cylindrical section oriented away from the insertion end runs into an adjacent cylindrical section, forming a stop. The inner diameter of the latter cylindrical section is smaller than the other cylindrical sections. The pipe connection also consists of a conduit whose flat end area comes to rest on the inner stop of the press-fitting after being inserted into the same. A nondetachable, tight pipe connection is produced by closing a pressing tool with at least two pressing plates encompassing the press fitting. During the pressing process, the pressing plates act on the torus, including the sealing ring placed therein, and on the cylindrical section of the press fitting oriented towards or away from the insertion end. The invention is characterised in that an element (14, 21) which only allows the inserted conduit (4) to move backwards axially within a fixed limit is situated in the area of the cylindrical section (9, 25) oriented away from the insertion end, the inside clearance of said element when not under stress being smaller than the smallest possible outer diameter (18) of the inserted conduit (4) in terms of tolerance.
